USI® STM32™ Nucleo expansion board for LoRa™

USI® in partnership with STMicroelectronics developed the LoRa® expansion board for STM32 Nucleo (I-NUCLEO-LRWAN1). This board is an integrated solution allowing anyone to learn and develop solutions using LoRa® and/or FSK/OOK technologies.

The I-NUCLEO-LRWAN1 features the USI® LoRaWAN™ technology module, addressing low-cost and low-power wide area network (LPWAN) which comes with embedded AT-commands stack pre-loaded.

The I-NUCLEO-LRWAN1 can be controlled from an external host such as NUCLEO-L053 boards, running the I-CUBE-LRWAN embedded software. This software provides the means to set up a complete LoRaWAN™ node.

The I-NUCLEO-LRWAN1 is LoRaWAN™ class A certified and sustains the class C.

The I-NUCLEO-LRWAN1 includes the USI® LoRaWAN™ module, Arduino™ connectors, a SMA connector, a 50 Ω antenna and three ST environmental sensors.

For more details about all the components of the LoRa®-Middleware library, refer to the STM32 LoRa®software expansion for STM32Cube user manual (UM2073).

The I-NUCLEO-LRWAN1 is supplied by a third party not affiliated to ST. For complete and latest information, refer to the third party GitHub page https://github.com/USILoRaModule/USI_I-NUCLEO-LRWAN1.
